Abstract
Description
Technical Field
[0001] The utility model relates to the field of mechanical structure maintenance equipment, in particular to a gear ring bushing lining replacement tool and a gear ring bushing lining replacement device. Background Art
[0002] Double-sided polishing machine is a high-precision and high-efficiency double-sided polishing processing equipment used for semiconductor silicon wafers, magnetic materials, sapphire, optical glass, metal materials and other hard and brittle materials. Its working principle is that the sanding belt is dragged by the transmission device and drives two parallel polishing heads to rotate relative to each other (or make rotational motion). The double-disc grinding method is adopted, so that the workpiece is squeezed by the two polishing heads and subjected to friction in two directions at the same time to achieve the purpose of finishing. At the same time, there is a very thin abrasive liquid film on the surface of the sanding belt, thereby improving the service life of the sanding belt. The use of double-sided polishing machine can improve the surface finish, processing accuracy and surface quality of parts, thereby improving the service life and reliability of mechanical equipment.
[0003] In the double-sided polishing machine, the gear ring bushing is a driving mechanism for the cruise ship. It is a wear-prone part that needs to be replaced regularly. However, during the replacement, it was found that Figure 1 As shown, the bushing is composed of an outer metal bushing skin and an inner wear-resistant lining. The replaced metal bushing skin is often less worn in actual use, so you only need to replace the lining to use it again. However, the bushing skin and the inner lining are thin and tightly connected. General pin-type ejection equipment cannot disassemble the two, and destructive disassembly is very likely to cause scratches on the bushing skin.
[0004] Therefore, the current overhaul and maintenance of double-sided polishing machines still involves replacing the entire bushing, which causes a certain amount of cost waste, and the spare parts cycle is long, affecting production progress. Summary of the invention

The base is provided, and the buried hole is connected with the third large diameter section to form a receiving cavity for the dropped liner, and at the same time, a setting plane is provided for the tooling body, thereby improving the stability of the tooling.
[0009] Preferably, the cross-sectional outer contours of the first body and the second body are the same, so as to facilitate the docking of the first and second bodies, and the second body can be used upside down, and the overall outer dimensions are uniform.
[0010] Preferably, the base is further provided with a sinking groove, the cross-sectional shape of the sinking groove is the same as the cross-sectional shape of the second body, and the second body can be placed in the sinking groove; the buried hole is located at the center of the bottom of the sinking groove.

[0011] Preferably, the ejector rod further comprises a pressure plate, and one end of the ejection section is vertically fixedly connected to the pressure plate, so as to facilitate the pressurization operation by the user.
[0012] Preferably, the ejector rod further comprises a guide section, the guide section is coaxially fixedly connected with the ejection section, and the diameter of the guide section is smaller than the diameter of the ejection section. The guide section is provided to make the ejection process smoother.
[0013] Preferably, the cross-sectional profile of the pressure plate is the same as the profile of the first body, so that the pressure plate can cooperate with the sink.
[0014] Preferably, the axial length of the ejection section is equal to the sum of the lengths of the first small diameter section, the first large diameter section, the second large diameter section and the second small diameter section.
[0015] On the other hand, the utility model also provides a gear ring bushing replacement device, including a pressure device, the pressure device includes a base component and a pressurizing component, and also includes the above-mentioned gear ring bushing lining replacement tooling, the base is installed on the base member, the first inner hole and the second inner hole are both arranged along the pressure action direction of the pressurizing component, and are located between the base component and the pressurizing component.
